RESUMEN
BACKGROUND: Most patients with hip fractures are elderly patients with comorbidities, and well-managed pain management is associated with positive postoperative outcomes. In recent years, new indications for regional anesthesia techniques have been defined, and they have found more place in clinical practice. Herein we investigate the effect of US-guided PENG block on positioning pain and compare that effect to intravenous opioid in patients undergoing surgery under spinal anesthesia for hip fractures. Additionally, we sought to investigate the effect of PENG block on pain scores, opioid intake, time to first analgesic requirement, and quality of recovery within the first 24 h following surgery. METHODS: In this study, patients were divided into the PENG (n = 42) and control group (n = 42) one hour prior to surgery. A team who was blinded to the assigned groups, collected and evaluated all data such as spinal anesthesia positioning pain, postoperative pain, opioid requirement. RESULTS: Patients that underwent PENG had statistically significantly lower NRS scores after interventions, immediately before positioning, at positioning and at end of spinal anesthesia. Pain scores during positioning for spinal anesthesia were statistically significantly lower in the PENG group than in the control group (p < 0.001). Total morphine use over the first 24 h was extremely statistically significantly lower in the PENG group (p < 0.001). CONCLUSIONS: Positive outcomes of PENG block in patient positioning pain before spinal anesthesia, postoperative pain scores, and morphine consumption are consistent with similar studies. High patient satisfaction in patients who underwent PENG block contributes to the literature. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04871061.

BACKGROUND: Biomarkers are useful for diagnosing infection and sepsis in adults, but data are limited in elderly patients. Furthermore, clinical symptoms of infection in elderly patients are usually atypical or unclear. We aimed to assess the usefulness of PCT, CRP, and WBC in distinguishing elderly patients infected with sepsis from infected without sepsis and those with no-infection. We also aimed to find a cut-off value for diagnosing sepsis and infection without sepsis in elderly critically ill patients. METHODS: In this single-center and prospective observational study, patients older than 65 years were enrolled. Serum levels of PCT, CRP, and WBC were measured within 24 h. Patients were allocated into sepsis (S), infected without sepsis (IWS), and noinfection (NI) groups. Data were analyzed with Mann-Whitney U test and Kruskal-Wallis test. RESULTS: We analyzed 188 patients with a mean age of 77.05 ± 7.4 in the study; 95 (50.5%) of them were women. Sixty-four (34%) of whom were classified as IWS, 29 (15%) as S, and 95 (50.5%) as NI group. There were significant differences in the PCT, CRP levels between the IWS and NI, S and NI (p < 0.001, p < 0.001, p < 0.001, p < 0.01, respectively). The PCT levels were significantly different when the NI group was compared to IWS (p < 0.001) and S (p < 0.001) groups. The CRP levels were also different when the NI group was compared to both IWS (p < 0.001) and S (p < 0.001). The PCT cut-off values were 0.485 µ/L and 1.245 µg/L for the discrimination of patients with IWS and S, respectively. The cut-off values of CRP level were 59.45 mg/L and 57.50 mg/L for infected without sepsis and sepsis, respectively. DISCUSSION: PCT was found to be a more valuable marker than CRP and WBC for the discrimination of elderly patients with infected without sepsis and sepsis.

OBJECTIVES: Although high procalcitonin (PCT) levels are associated with poor neurological outcomes and increased mortality rates in patients treated with targeted temperature management (TTM) in the postcardiac arrest (CA) period, there are limited data about the correlation between PCT levels and infection. The aim of our study was to assess the relationship of PCT levels in the first 48 hours with early period infections, late period neurological prognosis, and mortality in patients treated with TTM after CA. MATERIALS AND METHODS: Serum PCT was measured on admission days 1 and 2. The early onset infection diagnosis before the seventh day in the intensive care unit (ICU) was made according to the criteria of infection centers for disease control and prevention. Mortality and neurologic outcomes were assessed 90 days after CA according to cerebral performance category (CPC) score. RESULTS: There was no statistically significant correlation between early period infection diagnosis and PCT levels at the time of admission, 24th, and 48th hours. Patients with poor neurologic outcomes on the 90th day had significantly high PCT levels at 24 (p = 0.044) and 48 hours (p = 0.004). There was no statistically significant correlation between admission PCT levels and neurological prognosis. While the correlation between mortality and PCT levels at 24 (p = 0.049) and 48 (p = 0.004) hours was significantly high, no statistically significant correlation was found between admission PCT levels and mortality. CONCLUSION: In patients treated with TTM after CA, increased PCT levels were significantly correlated with poor neurologic outcomes and mortality. However, the elevated PCT levels were not significantly correlated with early period infections. HOW TO CITE THIS ARTICLE: Zincircioglu C, Yavuz T, Saritas A, Çakmak M, Güldogan IK, Uzun U, et al.

RESUMEN
Background/aim: To compare the inferior vena cava (IVC) indices, identify their variation rates at positive pressure values and accurate predictive values for the volume status in patients with spontaneous respiration receiving different positive pressure support. Materials and methods: The study included 100 patients who were divided into 4 pressure support groups, according to the different pressure supports received, and 3 volume groups according to their CVP values. Ultrasonography was applied to all of the patients to define their IVC diameters at different pressure supports. Dynamic parameters were derived from the ultrasonographic assessment of the IVC diameter [collapsibility (CI-IVC), distensibility (dIVC), and delta (ΔIVC) indices]. Results: There were significant differences between the 3 indices (CI-IVC, dIVC, and ΔIVC) according to the pressure groups [(10/5), (10/0), (0/5), (t tube 0/0)]. The median value for the dIVC percentages was ≤18% for all of the positive pressure support hypervolemic groups, apart from the hypervolemic t tube group (19%). For the hypervolemic groups, the best estimation according to the cut-off value appeared to be for the dIVC. Values with the highest sensitivity for differentiation of the hypovolemic individuals were calculated with the dIVC. Conclusion: The dIVC had a more accurate predictive role in predicting the volume status when compared with the CI-IVC and ΔIVC, and may be used reliably with positive pressure supports.

PURPOSE: The aim of our study is to research the role and efficacy of cerebral oximetry in predicting neurologic prognosis when applied during TTM to patients experiencing coma after CA. METHODS: This study was performed on surviving adult comatose patients after CA treated with TTM. The average scores of rSO2 was measured at 6h intervals for the first 2days and once a day for the following 3days with a NIRS device during TTM. The CPC scale was used to define the neurologic outcomes of patients. We compared the correlations of rSO2 values between good (CPC 1-2) and poor (CPC 3-5) neurologic outcomes in CA patients. RESULTS: There was no statistically significant difference identified between the prognosis groups in terms of rSO2, CPR durations, hemoglobin values and admission body temperature (p>0.05). When the variation in rSO2 values over time is investigated, though there was no significant difference between the good and poor prognosis groups, it appeared to fall in the first 6h in both prognosis groups. The median NT-proBNP and lactate values were observed to be higher in the poor prognosis group. CONCLUSION: There is no significant correlation between rSO2 values and neurologic outcomes. Multimodal monitoring methods may be useful and further studies with a larger patient population are necessary in this area.

Background/aim: Colistin is gaining popularity against multidrug-resistant bacteria. The primary concern with colistin is its nephrotoxicity (NT). The aim of this study was to evaluate the incidence and risk factors for NT and to evaluate the risk factors for mortality in the toxicity group. Materials and methods: NT was defined according to the RIFLE criteria. Data of patients who did or did not develop NT were compared. Positive and negative predictive values, risk ratio, and correlation coefficients were calculated. Results: NT was seen in 39 patients (70%). Hypoalbuminemia, old age, and the use of vasopressors (VPs) were associated with NT. The use of VPs had the highest positive predictive value, while age had the highest negative predictive value and risk ratio. The only variable that was associated with mortality in the toxicity group was VP use. Conclusion: Aging, hypoalbuminemia, and the use of VPs were shown to be risk factors for NT, while the last of these was the only significant risk factor for mortality in the toxicity group.
RESUMEN
AIM: To determine the incidences of anxiety and depression in relatives of patients admitted to an intensive care unit (ICU) and to investigate the relationships between psychological symptoms and demographic features of the patients and their relatives. METHODOLOGY: Relatives of 78 ICU patients were enrolled in the study. Sociodemographic features of patients and their relatives were recorded. The Turkish version of the Hospital Anxiety and Depression Scale was used to assess anxiety and depression. RESULTS: Twenty-eight (35.9%) cases with anxiety and 56 (71.8%) cases with depression were identified. The mean anxiety and depression scores were 9.49 ± 4.183 and 9.40 ± 4.286, respectively. Anxiety (P = .028) and concomitant anxiety with depression (P = .035) were more frequent among family members of young patients. The relationship to the patient, especially being a spouse, was significantly associated with symptoms (anxiety, P = .009; depression, P = .019; and both, P = .005). CONCLUSION: Spouses and family members of relatively young patients had higher rates of anxiety and depression. In contrast to the literature, depression was more common than anxiety among the relatives of ICU patients. Further research is needed on the impact of cultural and regional differences on anxiety and depression rates in family members of ICU patients.

Background: Vaccines against coronavirus disease-19 (COVID-19) have been effective in preventing symptomatic diseases, hospitalizations, and intensive care unit (ICU) admissions. However, data regarding the effectiveness of COVID-19 vaccines in reducing mortality among critically ill patients with COVID-19 remains unclear. Aims: To determine the vaccination status and investigate the impact of the COVID-19 vaccine on the 28-day mortality in critically ill patients with COVID-19. Study Design: Multicenter prospective observational clinical study. Methods: This study was conducted in 60 hospitals with ICUs managing critically ill patients with COVID-19. Patients aged ≥ 18 years with confirmed COVID-19 who were admitted to the ICU were included. The present study had two phases. The first phase was designed as a one-day point prevalence study, and demographic and clinical findings were evaluated. In the second phase, the 28-day mortality was evaluated. Results: As of August 11, 2021, 921 patients were enrolled in the study. The mean age of the patients was 65.42 ± 16.74 years, and 48.6% (n = 448) were female. Among the critically ill patients with COVID-19, 52.6% (n = 484) were unvaccinated, 7.7% (n = 71) were incompletely vaccinated, and 39.8% (n = 366) were fully vaccinated. A subgroup analysis of 817 patients who were unvaccinated (n = 484) or who had received two doses of the CoronaVac vaccine (n = 333) was performed. The 28-day mortality rate was 56.8% (n = 275) and 57.4% (n = 191) in the unvaccinated and two-dose CoronaVac groups, respectively. The 28-day mortality was associated with age, hypertension, the number of comorbidities, type of respiratory support, and APACHE II and sequential organ failure assessment scores (p < 0.05). The odds ratio for the 28-day mortality among those who had received two doses of CoronaVac was 0.591 (95% confidence interval: 0.413-0.848) (p = 0.004). Conclusion: Vaccination with at least two doses of CoronaVac within six months significantly decreased mortality in vaccinated patients than in unvaccinated patients.

UNLABELLED: The aim of this study is to investigate effect of enflurane that is a pro-convulsive anesthetic agent and propofol on seizure durations and recovery times during electroconvulsive therapy. METHODS: The subjects were divided into two groups according to the induction anesthetics. Anesthesia was induced with enflurane 5% in group E or propofol 1.2 mg x kg(-1) in group P. After the loss of consciousness, 0.5 mg x kg(-1) of succinylcholine was given. The patients maintained normocapnia. RESULTS: There were no significant differences between groups regarding seizure times. Recovery times were shorter in group E, but postictal agitation was significantly lower in propofol group. DISCUSSION: High incidence of spike activity on EEG and grand mal seizure patterns could be induced by enflurane. But motor and EEG seizure times were not prolonged by enflurane in the presence normocapnia. In conclusion, propofol is more suitable anesthetic agent for ECT, but enflurane might be preferred in patients because of rapid recovery.

Objectives Sepsis bundle compliance is not clear. We evaluated rates of compliance with sepsis bundle protocols among health care providers in Turkey. Methods Our study was carried out retrospectively. Forty-five intensive care units (ICU) participated in this study between March 2, 2018 and October 1, 2018. Results One hundred thirty-eight ICUs were contacted and 45 ICUs agreed to participate. The time taken for the diagnosis of sepsis was less than six hours in 384 (59.8%) patients, while it was more than six hours in 258 (40.2%) patients. The median [interquartile range (IQR)] times for initial antibiotic administration, culturing, vasopressor initiation, and second lactate measurement were 120.0 (60-300) minutes, 24 (12-240) minutes, 40 (20-60) minutes, and 24 (18-24) hours, respectively. The rate of compliance with tissue and organ perfusion follow-up in the first six hours was 0%. The rates of three- and six-hour sepsis bundle protocol compliance were both 0%. The ICU mortality rates for sepsis and septic shock were 22% and 78%, respectively. The ICU mortality rates for sepsis and septic shock were 22% and 78%, respectively. Conclusions The rate of compliance with sepsis bundle protocols was evaluated in Turkey for the first time and determined to be 0%.
RESUMEN
INTRODUCTION: We aimed to investigate the clinical features and mortality of critically ill patients treated with convalescent plasma for COVID-19 in the intensive care unit (ICU). MATERIAL AND METHODS: We retrospectively collected clinical and laboratory data of COVID-19 patients treated in the ICU. The patients were divided into two groups: those who received convalescent plasma and those who did not. We evaluated changes in the laboratory parameters and PaO2/FiO2 of the patients in the convalescent plasma group on days 0, 7, and 14. RESULTS: A total of 188 patients were included, 89 of whom received convalescent plasma. There were no significant differences in length of hospitalization [median: 17 vs. 16 days, P = 0.13] or 28-day mortality between the two groups (59% vs. 65%, P = 0.38). The ICU stay of patients who received convalescent plasma was longer (P = 0.001). The dynamics of the laboratory parameters of 44 patients in the convalescent plasma group, who were still in intensive care on the 14th day, were analysed. There was no differences in CRP or PaO2/FiO2 on day 0, 7 or 14 (P = 0.12; P = 0.10, respectively). CONCLUSIONS: Convalescent plasma treatment was not associated with shorter hospitalisation or lower mortality in patients diagnosed with COVID-19. However, the ICU stay was longer in patients who received convalescent plasma.

UNLABELLED: Ischemia/reperfusion (I/R) occurs in a number of pathological conditions, including myocardial infarction, stroke, aortic surgery, cardiopulmonary bypass surgery, organ transplantation, resuscitation, and critical care. Massive and abrupt release of oxygen-free radicals after reperfusion triggers oxidative damage. Before critical operations or after resuscitation, it would be wise to find a suitable prophylactic treatment to avoid I/R damage. We aimed to determine whether several commonly used intravenous anesthetics protect against renal I/R injury. METHODS: Animals were randomly divided into seven groups, each consisting of six animals: sham group, control group, thiopental group, propofol group, intralipid group, etomidate group, and ketamine group. At the end of the 60-min ischemic period, 60 min reperfusion was established and the materials administered 15 min before the reperfusion. At the end of the reperfusion period, the samples of blood and tissue were reaped for biochemical and serological evaluation. RESULTS: I/R procedure significantly increased malondialdehyde (MDA) levels, decreased catalase (CAT) activities, and superoxide dismutase (SOD) levels. The lowest MDA mean level was in the thiopental group and the highest MDA mean level was in control group. The lowest CAT mean level was in the intralipid group and the highest CAT mean level was in the etomidate group. The lowest SOD mean level was in the control group and the highest SOD mean level was in the propofol group. CONCLUSION: Thiopental and propofol, especially thiopental, are more effective to protect renal I/R injury.

BACKGROUND: Effective noninvasive mechanical ventilation (NIV) requires a patient to be comfortable and in synch with the ventilator, for which sedation is usually needed. Choice of the proper drug for sedation can lead to improved clinical outcomes. OBJECTIVE: The aim of this study was to compare the effectiveness of dexmedetomidine and midazolam on sedation and their effects on hemodynamics and gas exchange. METHODS: In this randomized, double-blind study, intensive care unit patients with acute respiratory failure due to acute exacerbations of chronic obstructive pulmonary disease undergoing NIV were equally randomized to receive a loading dose of 1 µg/kg IV dexmedetomidine or 0.05 µg/kg midazolam over 10 minutes followed by a maintenance infusion of 0.5 µg/kg/h dexmedetomidine (group D) or 0.1 mg/kg/h midazolam (group M). The following parameters were measured by a blinded clinician at baseline and 1, 2, 4, 6, 8, 12, and 24 hours after the loading dose was administered: Ramsay Sedation Score (RSS), Riker Sedation-Agitation Scale (RSAS), Bispectral Index (BIS), arterial blood gases, and vital signs. A second blinded investigator determined dosing changes according to the outcome of maintaining a target sedation level of RSS 2 to 3, RSAS 3 to 4, and BIS >85. RESULTS: A total of 45 patients were assessed for enrollment in the study; 4 did not meet the inclusion criteria and 1 refused to participate (men/women 19/21; mean age 58/60; all patients were receiving bronchodilators, steroids, antibiotics, and mucolytics). In both groups (n = 20), RSS significantly increased and RSAS levels and BIS values significantly decreased after the loading dose, compared with baseline (P < 0.05). RSS levels were significantly lower beginning at 4 hours in group D compared with group M (P < 0.05). RSAS levels were not significantly different between the 2 groups in the first 8 hours. However, RSAS levels were significantly higher at 8 hours after the loading dose was administered in group D compared with group M (P < 0.01). BIS was significantly higher in group D throughout the study period (P < 0.05). Respiratory rates and gas exchange values were not significantly different between the Accepted for publication April 7, 2010. 2 groups. The number of times a change in infusion dose was needed was significantly lower in group D (2 patients with 1 change each) than in group M (3 patients with 1 change, 1 patient with 2 changes, and 3 patients with 3 changes each) (P < 0.01). CONCLUSIONS: Dexmedetomidine and midazolam are both effective sedatives for patients with NIV. Dexmedetomidine required fewer adjustments in dosing compared with midazolam to maintain adequate sedation.
RESUMEN
STUDY DESIGN: Needle orientations for lumbar and cervical facet injection were measured in cadavers and compared with facet angles measured on magnetic resonance images (MRIs). OBJECTIVES: To establish facet orientation relative to clinical procedures of a facet joint block in the cervical and lumbar spine. METHODS: Needle orientation angles were measured from 20 unembalmed human cadaveric specimens (13 cervical and 7 lumbar). Spinal needles were inserted into the midpoints of the facet joint spaces from C3 to C7 and L1 to L5. Needle trajectories were measured with an optical tracking system. For comparison, facet angles from 100 clinical MRIs of lumbar spines were also measured. Facet orientations on MRIs were measured at their intersection with the transverse plane, and angles were quantified using image analysis software. RESULTS: Typical angles for insertion of the needle into the cervical facets were oriented closer to the coronal plane, whereas insertion angles for lumbar needles were oriented closer to the sagittal plane. Relative to the sagittal plane, the mean cervical angle was 72 degrees and the mean lumbar angle was 33 degrees. The insertion points of the cervical facets were a mean of 29 mm from the midsagittal plane compared with a mean of 22 mm for the lumbar facets. MRI-based facet joint angles correlated poorly with actual injection angles, which were overestimated 5 to 23 degrees, depending on the lumbar level. CONCLUSIONS: Knowledge of the quantitative anatomy of the facets may help improve clinical diagnosis and treatment. These data also may aid in constructing more realistic computer simulations.

OBJECTIVES: To compare the effect of three different suction pressures (80 mmHg, 150 mmHg, 250 mmHg) with the open system suction method in terms of the volume of secretions and complications development in intubated intensive care patients. RESEARCH METHODOLOGY/DESIGN: This study was planned as a prospective, experimental, self-controlled design. The study sample included 47 patients. Data were collected using a data collection and patient follow-up form from patient records. SETTING: Single adult intensive care unit in a university hospital. RESULTS: Fifty five percent of the patients were male, 61.7% were older than 65 years and 38.32% had lung infection. The amount of suctioned secretions tended to increase significantly with increasing negative pressure and there was a significant difference between the pressures in terms of the median volume of suctioned secretions (p < 0.001). There was no significant difference between the suction pressures in terms of oxygen desaturation, hypertension rates (p > 0.05). Tachycardia, bradycardia, hypoxaemia, tracheal mucosal damage or mucosal bleeding were not observed during suctioning with three different suction pressures. CONCLUSION: It may be assumed that 250 mmHg suction pressure, via compliance with open system suction method related procedures, is being more effective and equally safe for secretion cleaning in comparison to the 80 and 150 mmHg suction pressures.

BACKGROUND: Pneumoperitoneum (P) created to facilitate laparoscopy (L) is associated with splanchnic hypoperfusion, ischemia/reperfusion (I/R) injury, and oxidative stress. AIM: This study investigated the effects of pre- and post-laparoscopic conditioning, zinc, pentoxifylline (PTX), and N-acetylcysteine (NAC) on markers of I/R injury in an animal model. METHODS: Sprague-Dawley male rats (n = 56, weight range 300-350 g) were randomly placed in one of seven treatment groups. Except for group C (control group who underwent a sham operation without pneumoperitoneum), pneumoperitoneum was created in all using CO(2) insufflation under a pressure of 15 mmHg. Group L (laparoscopy) was subjected to 60 min of pneumoperitoneum. Group Lpre (laparoscopic preconditioning plus laparoscopy) was subjected to 5 min of insufflation and 5 min of desufflation followed by 60 min of pneumoperitoneum. Group Lpost (laparoscopy plus laparoscopic post-conditioning) was subjected to 60 min of pneumoperitoneum and 60 min of desufflation followed by 5 min of insufflation and 5 min of desufflation. The laparoscopy plus zinc (LZ), PTX (LP), and NAC (LNAC) groups received a single intraperitoneal injection of zinc (50 mg/kg), pentoxifylline (50 mg/kg), or N-acetylcysteine (150 mg/kg) 5 min before the desufflation period. Animals were sacrificed at the end of the experiments, and kidney samples were tested for malondialdehyde (MDA), catalase (CAT), glutathione peroxidase (GPX), and superoxide dismutase (SOD). RESULTS: MDA levels, as an indicator of oxidative stress in kidney tissue samples, were significantly higher in all pneumoperitoneum groups compared to Group C, except for Group Lpre. The pattern of change in tissue levels of SOD, GPX, and catalase was variable in the different treatment groups. CONCLUSIONS: In this animal model of renal ischemia/reperfusion injury, laparoscopy caused renal ischemia as evidenced by elevated markers of tissue ischemia-reperfusion injury. This effect was significantly attenuated by post-laparoscopy conditioning, zinc, pentoxifylline, and N-acetylcysteine, but not by pre-laparoscopy conditioning.

BACKGROUND: The treatment of sAVF is difficult, and many therapeutic approaches have been proposed. General approaches for the treatment of sAVF include ligation of the feeding arteries, surgical removal, electrothrombosis, embolization, and a combination of these approaches. CASE DESCRIPTION: A 35-year-old man presented with occipital subcutaneous pulsatile thrill. We discussed and illustrated a rare sAVF, which was a high-flow sAVF fed by the occipital branch of the right ACE draining intraosseously into the SS. The case was treated by surgical origin ligation. CONCLUSION: This case was unusual in the sense that it was apparently spontaneous, and the major venous drainage was through the bone into the SS. Arterial supply pattern of sAVF is very important in therapeutic decision-making. We suggest that surgical origin ligation for sAVF be considered if the case has 1 feeding artery.

Previous data have shown that preoperative analgesia may reduce postoperative analgesic demands. The aim of the current study was to determine if preincisional ropivacaine infiltration may reduce postoperative oral pain in infants and small children undergoing elective cleft palate patients.Twenty nonsyndromic cleft palate patients were randomly divided into 2 groups. Injection with ropivacaine hydrochloride, at dose of 0.2 mg/kg, was performed by submucous infiltration of the proposed incisional site groups of patients. In control group, no medication was given before cleft palate repair under general anesthesia. Postoperative pain scores were measured according to Children and Infants Postoperative Pain Scale. Heart rate recordings and noninvasive blood pressure measurements were also done in all the patients.Measurements of Children and Infants Postoperative Pain Scale scores at all the observational postoperative periods showed significantly favorable values in ropivacaine group than in control group (P < 0.05). Six patients in the control group required rescue analgesia, whereas 2 patients required analgesic therapy in the treatment group.Preemptive analgesia using ropivacaine may enhance early postoperative comfort by reducing early postoperative pain in primary cleft repair.

OBJECTIVE: The accelerative effect of EMLA (eutectic mixture of lidocaine 2.5% and prilocaine 2.5%) in the wound healing process is known. We hypothesised that post-operative peritoneal adhesions may be reduced with intra-peritoneal EMLA administration in a model of bacterial peritonitis. STUDY DESIGN: Bacterial peritonitis was induced in 24 rats by cecal ligation and puncture. The rats were randomly assigned to one of four groups. Group 1 (n=6)) received EMLA intraperitoneally, group 2 (n=6) received 2% lidocaine hcl solution intraperitoneally, the third group received one dose (100 mg/kg) of ceftriaxone sodium (Rocephin, Roche, 1 g) intraperitoneally one day after cecal ligation and puncture procedure, and in control group (group 4, n=6), no fluid or medicine was introduced into the abdomens of the rats. All animals were killed 14 days later in order to assess the adhesion score. Tissue antioxidant levels were measured in 1 g tissue samples taken from the abdominal wall. RESULTS: The adhesion score was significantly lower in the EMLA group than in the lidocaine and control groups. The catalase levels were higher in the lidocaine and control groups than in EMLA group. CONCLUSIONS: Intraperitoneal EMLA inhibited the formation of postoperative intra-abdominal adhesions without compromising the wound healing in this bacterial peritonitis rat model. EMLA also decreased the oxidative stress during peritonitis (Tab. 1, Fig. 7, Ref. 27). Full Text (Free, PDF) www.bmj.sk.

OBJECTIVES: Our aim was to investigate the most common problems in diagnosing brain death, the care of the organ donor, and organ donation after death. MATERIALS AND METHODS: A survey was sent randomly to clinicians working in national intensive care units in Turkey. The survey, which consisted of 17 questions for clinicians, had 163 responders. RESULTS: The most common cause of brain death was traumatic brain injury. Although 22% of clinicians found the apnea test necessary for brain death diagnosis, 78% stated that it could be used as an optional confirmatory test. However, 65.6% of the clinicians were not familiar with the modified apnea test. The most frequently used vasoactive agent for hypotension in patients with brain death was noradrenaline (54.6%) and dopamine (41.6%). Regarding time of death, 50.3% of clinicians considered it as the time and date when the patient was diagnosed with brain death and 47.8% as the time and date of cardiac arrest. When asked whether they terminate the treatment of a patient with brain death when organ donation is rejected, only 16.1% discontinued all advanced life support. According to the survey, the most common reason for not accepting organ transplant was for religious reasons. CONCLUSIONS: In intensive care units, differences in definitions and care of patients with brain death continue to be a complication. There has been a lack of progress in criterion standards of brain death diagnosis and donor care, as verified by our survey.
